Branching patterns and symmetry of the course of the facial artery in Koreans

Aim of our study was to evaluate the prevalence of aberrant origin of the branches of the external carotid artery (ECA) in 97 patients by computed tomography (CTA) and magnetic resonance angiography (MRA) and to compare the accuracy of these two techniques in the visualization of the ECA system. All patients underwent CTA and MRA examination of the head and neck. Multiplanar and volumetric reformations were obtained in all cases. For each set of images, the presence of aberrant origin of the branches of the external carotid artery was investigated. MRA and CTA images of each patient were compared to define their information content. Anatomical anomalies were found in 88 heminecks, with a prevalence of 53.3%. In the 61 patients in whom the CTA was performed before the MRA, the latter method showed only 92% of abnormalities detected at the first examination; in the 36 patients in whom MRA was performed first, CTA identified all of the anomalies highlighted by the former, adding 12 new. Knowledge of the anomalies of origin of the ECA branches is essential for the head and neck surgeon; the high prevalence of anomalies found in our series as in the previous studies indicates the opportunity to perform a CTA or a MRA of the head and neck before any surgical or interventional procedure. CTA is the method of choice in the evaluation of anomalies of origin of the branches of the ECA and in the definition of their course.

“…The prevalence found in our series for this variation is very close to that reported in the literature (7.5-20%) [14,26,29,39].…”

“…It enters the face at the lower mandible anterior to the masseter muscle and runs upward and forward tortuously toward the angle of the mouth. Previous studies have shown that there is a racial variation in the origin and the branches patterns of the facial artery (Koh et al, 2003;Nakajima et al, 2002;Niranjan, 1988). Facial vessels are widely used in plastic surgery as the pedicle of some flaps (D'Arpa et al, 2009;Hofer et al, 2005;Joshi et al, 2005;Pribaz et al, 1992;Yamauchi et al, 2010).…”

SUMMARY:The aim of this study was to investigate the course of the facial vessels according to several mandibular landmarks in living individuals using multidetector computed tomography angiography (MDCTA) to determine these related to sex and side. This study was conducted in the Radiology Department, Meram Faculty of Medicine, Necmettin Erbakan University (Konya, Turkey). In total, sixty faces from 30 specimens (15 males and 15 females) with symptoms and signs of vascular disease were evaluated for the facial vessels by MDCTA scan. The facial vessel parameters were measured according to the reference points (mandibular angle, mental protuberance, mental foramen and facial midline). The distance from the point at which the facial artery first appears in the lower margin of the mandible to the mandibular angle for right and left facial artery were observed as 3.53±0.66 cm and 3.31±0.73 cm in males, respectively. These distances were determined as 2.91±0.52 cm and 3.35±0.48 cm in females. MDCTA is a new, powerful, safe and noninvasive test to demonstrate the vasculature of the head. Bony structures and neighboring vessel morphology can be evaluated by this technique in cases of trauma with suspected vessel injuries and when considering patient selection for flap surgery.

“…Its branches in the face include: inferior labial artery, to the lower lip; superior labial artery, to the upper lip; lateral nasal artery, to supply the ala and dorsum of the nose (Standring, 2008). The reported variations of the facial artery include: its intra parotid origin (Nayak, 2006); arising as a common trunk with the lingual artery as linguofacial trunk (Midy, Mauruc, Vergnes et al, 1986); its function being taken over by maxillary artery, transverse facial artery or the nasal branch of ophthalmic artery when absent (Bergman et al, 1988); its termination as submental artery, labial artery or lateral nasal artery (Bergman et al, 1988); and, a case of duplex artery (Koh et al, 2003). However, in the case studied, we noticed a variation in the morphological aspect of arterial pattern of face, until then not documented.…”
